Duvet covers in Danish sizes

Short answer: The cover has to fit the duvet and not the bed. The common Danish sizes are one hundred and forty by two hundred and two hundred by two hundred and twenty.

The duvet decides the size

A single duvet is typically one hundred and forty by two hundred centimetres. A double is two hundred by two hundred and twenty. With a long duvet there are covers in a two hundred and twenty length for both widths.

Too large or too small

If the cover is too large, the duvet bunches at one end. If it is too small, the duvet is compressed and insulates less well. You notice either on the first night. See bamboo bedding.

The closure

Most Danish covers close with buttons or with an open flap. A flap makes filling easiest, while buttons hold best if you turn a lot. See bamboo pillowcases.

Sets or separate pieces

Buying a set gives you a cover and a matching pillowcase. If you have two duvets in one bed, you need two sets for one bed. See bamboo home and homewear.

Frequently asked questions

How much does a cover shrink

A few percent in the first wash. Do not choose a size that only just fits.

Can a cover that is too long be used

Yes, but the duvet gathers at the bottom. A button in the middle can hold it.

What if my duvet is an unusual size

Then measure it and buy by the number. Covers come in more sizes than the two common ones.
